IPC: B04C9/00
Filed: 1985-12-11
Abstract: PURPOSE:To remove the foreign matter in steam by utilizing inertial force, by connecting one contraction pipe receiving steam from a boiler to a branch pipe having two piping parts different in a radius of curvature. CONSTITUTION:A branch pipe 7 having a contraction pipe 6 is used between a boiler 1 and a steam turbine main steam stop valve 2. In starting a steam turbine, the steam stop valve 3 is fully closed at first and bypass valves 4, 5 are fully opened. Steam passing through the bypass valve 4 enters the contraction pipe 6 and respectively divided into steam containing impurities to piping 8 and clean steam containing no impurities to piping 9 by the difference of inertial force. Clean steam is introduced into the steam turbine through the bypass valve 5 and the main steam stop valve 2 and steam containing impurities is introduced into a cyclone separator 10. The clean steam from which foreign impurities were removed by the cyclone separator 10 is introduced into the inlet side of the main steam stop valve 2 or a boiler reheating steam system through piping 11 and the stop valve 12.

Namely, the lens having the curvature on both faces is used in order to correct the basic aberrations at a reference wavelength. The diaphragm and the lens are arranged sufficiently apart in order to obtain the good balance of the performance of the entire image plane while adequately correcting coma aberrations.  At least one face is composed of the diffractive face, by which the chromatic aberration correction by the effect of the diffractive face and the effect of the diffraction system is made possible. The high performance which is impossible with the conventional refractive lens is achieved in spite of the single lens.

Title: Device for measuring solder wettability
Inventor: SAITO MASARU
IPC: G01N13/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To measure solder wettability even in a wire diameter that is small and cannot be easily measured due to slight disturbance by feeding a penetration member into melting solder in a soldering tank by a driving member for raising a liquid surface, and by detecting wetting stress being applied to a sample. SOLUTION: In a first tank 2a of a soldering tank 2, a sample T is locked on a liquid surface while the sample is not in contact with the liquid surface. In a second tank 2b, an immersion block 10 is set so that the immersion block can be moved in a vertical direction for the liquid surface. A liquid surface adjustment unit 9 allows the immersion block 10 for adjusting the liquid surface to be gradually immersed in solder S, and the level of the liquid surface is adjusted so that the bottom of the sample T is in contact with the melting solder S. After time is measured, when the sample T is immersed by specific length, the dip block 10 is stopped. Although the sample T is immersed in the melting solder S and buoyancy operates, the sample T is pulled into the tank 2 after the wetting of the solder is generated with time and the buoyancy becomes equal to wetting stress. The immersion block 10 is pulled up for completing measurement after the dip block 10 is immersed for a specific time period.

Abstract: PURPOSE:To realize a photographing focusing an object by calculating a defocus amount based on an output from a light receiving means and deciding a stop value at which an object is within a focal depth or a depth of field, according to the defocusing amount. CONSTITUTION:When a photometric switch sw1 is turned on, a photometric value is fetched from a photometric means 6 by an arithmetic means 3, a range is found by a range-finding means 5, and the defocusing amount on an image surface is attained. Based on this defocusing amount, an arithmetic means 3 calculates the stop value, at which a detecting focal position at a photometric point in the center of an image surface and a present focal position of an optical system are both within the depth of field, and which is displayed by a display means 4. On the other hand, when the release switch sw2 is turned on, an arithmetic means 3 outputs the stop value and a shutter release time into the exposure control means 7, which carries out exposure. Thus, a picture focusing on all the objects that is located in the detecting focal position at the photometric point and the present focal position of the optical system, and that is located between them, can be taken.

Title: Manufacture of thermoplastic resin formed sheet
Inventor: NODA YOUICHIROU
IPC: B29C44/00
Filed: 1988-11-02
Abstract: PURPOSE:To obtain a foamed sheet having no wrinkles or recession and protrusion, and being smooth in its surface by heating and foaming a foam sheet having a specific melt viscosity in making it to be press-contact with a supporting member being smooth in its surface and having no permeability. CONSTITUTION:A foam sheet 3 is foamed in the form of being cross-contact with a supporting member 6. In this instance, the decomposition gas pressure of a foaming agent functions in a three dimensional direction. In the decomposition temperature of the foaming agent, as the resin being 2X10<4> poise in the melt viscosity in the case of 10sec<-1> shearing speed is employed, the gas pressure acting to the longitudinal direction and width direction is small in being transmitted to the supporting member via the resin due to the low viscosity, and thus, the sheet being in the foaming period may never be torn off from the supporting member 6. By this reason, the sheet 3 foams mainly in the thickness direction, therefore, the occurrence of the wrinkles of a foam sheet 8 is prevented thereby. There is no space between the sheet 3 in the foaming period and the supporting member 6 in which air and the decomposition gas of the foaming agent are likely to remain uniformly, as a result, there never occurs any recession and protrusion in the foam sheet 8.
